The Fourth Circuit Court of Appeals, on a rehearing of a case en banc, held in United States v. Robinson, 2017 WL 280727 (Jan. 23, 2017), that an officer had the authority to conduct a frisk of a lawfully-stopped person whom the officer reasonably believed to be armed with a concealed firearm, regardless of whether the person may have been legally entitled to carry the firearm. This post discusses the ruling and its possible influence in the development of the law of frisk in North Carolina state courts. [For those who received my summary of this case as a subscriber to the criminal law listserv, this is the same summary but with the addition of an analysis and comment section at the end of this post.]
